Supported network services and their default network port numbers
In Digi devices that have multiple serial ports, the network port number defaults for
various services are set based on the following formula:
base network port number + serial port number
For example, the Telnet Passthrough service is set to network port 2001 for serial port 1,
2002 for serial port 2, 2003 for serial port 3, etc.
If a network port is changed for a particular service, that is the only network port number
that changes. That change does not carry over to the other network ports. For example, if
the network port number for Telnet Passthrough is changed from 2001 to 3001, that does
not mean that the other network ports will change to 3002, 3003, etc.
There are two types of network services available:
Basic services, which are accessed by connecting to a particular well-known
network port.
Passthrough services, in which a particular serial port is set up for a particular
type of service. To use the service, users must both use the correct protocol and
specify the correct network port. For example, assuming default service ports
and using a Linux host, here is how a user would access the SSH and Telnet
passthrough services:
#> ssh -l fred digi16 -p 2501
#> telnet digi16 2101
